Direct Observation of the Complex Formation of GDP-Bound Transducin with the Rhodopsin Intermediate Having a Visible Absorption Maximum in Rod Outer Segment Membranes
Rhodopsin is a photoreceptive protein that is present in rod photoreceptor cells, inducing a GDP−GTP exchange reaction on the retinal G-protein transducin (Gt) upon light absorption. This exchange reaction proceeds through at least three steps, which include the binding of photoactivated rhodopsin t...
